Edit: Or, another way. Is there a way I could have two Opt-out placeholders, one for each language I'm supporting?

Reason: Trying to be compliant with local law in French-Canadian Quebec. I can't assume either English or French on the part of the respondent. An acceptable solution would be if I could add both lang=en and lang=fr versions of the Survey and opt-out URLS to the email. But the token systems forces me one or the other as far as I can see.
